Operating the DSP Features

31-band Graphic Equalizer
A graphic equalizer is an essential tool for live events,
where a little contouring of your output signal may be
necessary. It can help reduce feedback and make your
audio sound altogether 'whole'. Setting your GEQ can
depend on a number of factors, including the timbre of the
instruments you're using, the positioning of microphones
within your venue, and the size and shape of the venue
itself. Tools like the Phonic PAA3 can be utilized to help
calculate suggested GEQ settings.
The iAMP DSP features a 31-band graphic equalizer on
each of the two output channels. There are, of course, 31
different frequencies between 20 Hz and 20 kHz that can
be adjusted by a rate of ±15 dB.
It is possible to link channel 1 and 2 so that the GEQ
settings of one channel will be copied to other. When
selecting the "Link" feature the direction that settings will
be copied is indicated by arrows.
Any GEQ settings can be reset using the "Reset" option.
Doing so will return the boost/cut for each frequency of the
31-band GEQ back to 0 dB.
The iAMP graphic equalizer features a number of presets,
including "Jazz", "Pop" and "Flat", among others. These
can be recalled within the 31-band GEQ submenu by
selecting LOAD and recalling the program. Select [Yes] to
then recall the preset.
There are also 8 user-definable save slots for your own
GEQ settings. These can be saved by selecting SAVE
followed by the save slot you wish to use. Unlike "Scenes"
(detailed later in this manual) these saved slots cannot be
renamed.
The GEQ for each channel can also be turned on and off.

Input Settings
The input settings on the iAMP are quite simple. You're able
to adjust the incoming signal levels (volume), of course,
as well as link channel 1 and 2 settings together. When
channels are linked, settings on one channel will be applied
to the other. The direction of the arrows when the link mode
is selected will determine which channel's settings will be
copied to which.
In addition to this, you have selectable input modes. The
two settings are "Stereo" and "Mono(In1)". In Stereo mode,
the channel 1 and 2 inputs will be sent to their respective
outputs. When, however, you select the mono option,
the channel 1 input will automatically be sent to both the
channel 1 and channel 2 outputs.
